All the bushings in the front are cracked or disinegrating. My car is all over the place over bumps. Sometimes it feels like I'm going to fishtail around bends. My struts need to be changed too (that may have something to do with it). In the past I've had vibration probs with my 19's on but fine when I put on 16's.

Do you know what bushings I need to ask for when I go to the dealer (or where ever).

I've got a set of Energy Suspension LCA bushings sitting in my garage that I'll sell you if you like.
